5 Evolution Site-Related Lessons From The Pros

Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, there are still misconceptions about the evolution. People who have absorbed the nonsense of pop science often believe that biologists claim they don't believe in evolution.

This rich Web site, which is a complement to the PBS program, provides teachers with materials which support evolution education while avoiding the types of misconceptions that can make it difficult to understand. It's organized in a "bread crumb" format to facilitate navigation and 에볼루션 바카라 무료체험 바카라 에볼루션사이트 (his explanation) orientation.

Definitions

It's difficult to effectively teach evolution. It is often misunderstood by non-scientists, and even some scientists are guilty of using a definition that confuses the issue. This is especially true when it comes to discussions on the meaning of the word itself.

It is therefore important to define the terms that are used in evolutionary biology. Understanding Evolution's website does this in a simple and efficient manner. The site is a companion site to the series that first aired in 2001, but is also an independent resource. The content is presented in a way that aids navigation and orientation.

The site defines terms like common ancestor, the gradual process and adaptation. These terms help to define the nature and relationship of evolution to other scientific concepts. The website provides a summary of the manner the concept of evolution has been tested. This information can help dispel the myths created by creationists.

It is also possible to get a glossary of terms used in evolutionary biology. These terms include:

Adaptation: The tendency for 에볼루션 바카라 (more information) hereditary traits to become more suited to a particular environment. This is a result of natural selection. It occurs when organisms that are better-adapted traits are more likely survive and reproduce than those with less adaptable characteristics.

Common ancestor (also called common ancestor) is the most recent ancestral ancestor shared by two or more species. By analyzing DNA from these species, it is possible to identify the common ancestor.

Deoxyribonucleic acid: A huge biological molecule that contains information necessary for cell replication. The information is contained in nucleotides arranged in sequences that are strung together to form long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information within cells.

Coevolution is a relationship between two species in which the evolutionary changes of one species are influenced by evolutionary changes in the other. Coevolution is evident through the interaction between predator and prey, or parasites and hosts.

Origins

Species (groups of individuals that can interbreed) change through a series of natural changes in the traits of their offspring. Changes can be caused by numerous factors, like natural selection, gene drift, and mixing of the gene pool. The evolution of new species can take thousands of years. Environmental conditions, such as changes in the climate or competition for food resources and habitat, can slow or accelerate the process.

The Evolution site tracks through time the emergence of various species of plants and animals and 에볼루션 바카라 focuses on major changes in each group's history. It also focuses on the human evolutionary roots, a topic that is particularly important for students to comprehend.

Darwin's Origin was written in 1859, when just a handful of antediluvian fossils of humans had been found. One of them was the infamous skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap when it was published in 1858, one year following the initial edition of The Origin.

The site is mostly one of biology, but it also contains lots of information about geology and paleontology. One of the most appealing features of the website are a timeline of events which show how climatic and geological conditions have changed over time as well as an interactive map of the distribution of some fossil groups listed on the site.

While the site is a companion to the PBS television show however, it can stand on its own as a great resource for teachers and students. The site is very well-organized and has clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated components of the museum's Web site. These hyperlinks help users move from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are links to John Endler's experiments with guppies, which illustrate the importance ecology in evolutionary theory.

Diversity

The evolution of life on Earth has produced a diversity of plants, animals, and insects. Paleobiology is the study of these creatures within their geological context is a superior method of study over modern observational or experimental methods of studying evolutionary processes. Paleobiology can examine not only processes and events that take place regularly or over time, but also the distribution and frequency of different species of animals across geological time.

The website is divided into various ways to learn about evolution, including "Evolution 101," which takes the viewer on a line through the nature of science and the evidence supporting the theory of evolution. The course also focuses on common misconceptions about evolution and the evolution theory's history.

Each of the other major sections of the Evolution site is equally well constructed, with materials that can support a variety of curriculum levels and pedagogical styles. The site offers a wide array of interactive and multimedia resources that include animations, video clips and virtual labs as well as general textual content. The breadcrumb-like organization of the content assists with navigation and orientation on the large website.

The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" gives a brief overview of coral relationships and their interactions with other organisms and zooms in on a single clam, which is able communicate with its neighbors and respond to changes in conditions of the water that occur at the reef level. This page, as well as the other multidisciplinary, multimedia and interactive pages on the site, provide an excellent introduction to a wide variety of topics in evolutionary biology. The information also includes an explanation of the role of natural selection and the concept of phylogenetic analysis which is a crucial tool for understanding the evolution of change.

Evolutionary Theory

Evolution is an underlying thread that runs through all branches of biology. A vast collection of books helps in teaching evolution across all life science disciplines.

One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of an Web page that provides depth as well as breadth in terms of its educational resources. The site has a wide array of interactive learning modules. It also has an "bread crumb structure" that allows students to move away from the cartoon style used in Understanding Evolution and onto elements on this site that are more closely linked to the worlds of research science. For instance an animation that explains the notion of genetic inheritance leads to a page highlighting John Endler's experiments in artificial selection with guppies in native ponds of Trinidad.

The Evolution Library on this website has a huge multimedia library of resources that are associated with evolution. The content is organized in the form of curriculum-based pathways that are in line with the learning objectives outlined in the biology standards. It includes seven short videos intended for use in the classroom. These are available to stream or purchase as DVDs.

Evolutionary biology remains a field of study with a lot of important questions, including what triggers evolution and the speed at which it happens. This is especially true in the case of human evolution which was a challenge to reconcile religious beliefs that humans have a distinct position in the universe and a soul, with the idea that innate physical traits were derived from the apes.

There are also a number of other ways in which evolution can take place, with natural selection as the most popular theory. Scientists also study other kinds such as genetic drift and sexual selection.

While many scientific fields of study are in conflict with literal interpretations in religious texts, the concept of evolution biology has been the subject of intense controversy and opposition from religious fundamentalists. Certain religions have embraced their beliefs to evolution but others haven't.
